He should have a bunch of single and dual channel units in new-like condition for sale. That should be superb bang for buck. |

I was thinking if a cheap PS costs £50 to £80 while it may do the job, the PSU is the heart of all your projects so it's probably one area you really shouldn't cheap out on, so is there anything in the £100 to £150 range that would be a no brain buy, either second hand or new ? or is £100 to £150 still considered "cheap" range ? |

You'll want more than one power supply anyway. I probably have 2 or 3 on my bench at any given time, some commercially made, some I built myself, some fancy, some as simple as a wall wart. |

Is that good enough? ;D Many folks seem to like them, myself included. Other than an issue with an earlier batch there don't seem to be horror stories about them. It's hard to beat that bang for buck, especially when you get a good deal on a second hand unit. |
